Sharing disk image between Mini vMac and PiSCSI/RaSCSI

[nsputnik]

I can't find a disk image file format that I can create with PiSCSI (formerly known as RaSCSI for Mac) that I can open in Mini vMac for current MacOS (in my case Intel, OSX 10.13). The PiSCSI's server has a web interface control panel for mounting and creating disk image that can read/write on a real Mac. So far I have tried .hda, .hdr, .hds, .hd1. I can format and mount them all on the Mac but can't open them in Mini vMac. I know Mini vMac for works mainly with .dsk files. SheepShaver can read .dmg, .dsk, and .hda created with PiSCSI with no problem. I know I can use SheepShaver as a bridge for just moving files or change .dsk to .dmg to mount in the host OS but I need to write files directly from a floppy to the PiSCSI image and then mount that in Mini vMac. Any ideas?

After a little more Googling I found a solution, Jean-Michel Durand's Disk Jockey app for both MacOS and Windows. https://diskjockey.onegeekarmy.eu/ It converts between Mini vMac mountable .dsk to a PiSCSI mountable .hda. It can go back the other way too, converting a .hda mountable PiSCSI back to a to .img which is really a just Mini vMac mountable image (which you can even rename .dsk to keep it consistent and it will still mount in Mini vMac).

PiSCSI and RaSCSI will make full disk images, including the SCSI driver partition. Mini vMac only uses the HFS partition. Mini vMac can also use Disk Copy images, however; the issue is that everything Mini vMac uses is a floppy disk, even if it's 1GB in size. Your SCSI images are, of course, hard disk images and not floppy images, which is why the conversion is necessary.

For working with HFS images on a Mac, I recommend https://thejoelpatrol.github.io/fusehfs/ which lets Disk Utility and the Finder interact with HFS images natively again.

Hi,

Mini vMac uses plain HFS images instead of full disk images which also include the partition table and driver partition. It's however possible to use Mini vMac to prepare a HFS image for later usage with RaSCSI/ZuluSCSI/BlueSCSI by first installing the system to your like and then following http://www.codesrc.com/mediawiki/index. ... romScratch to build a complete disk image.

With kind regards,
Egon

His version allows the use of BlueSCSI/PiSCSI images and ISO images.

Lovely... how does Eric feel about becoming the new maintainer? We still haven't heard from Paul since May 2021....
